PROPELLING APPARATUS FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 637,051, dated November14, 1899.

Application filed m 15, 1899.

To all whom it may concern.-

Be it known that I, CARL WASEK, a citizen of the United States, residingin Paterson, in the county of Passaic and State of New Jersey, haveinvented certain new and useful Improvements in Propelling Means forBoats; and I do hereby declare the following'to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

This invention relates to means for propelling small boats, and it hasreference particularly to that class of such propelling means whichdepends upon man-power for its actuation. The invention consists in thecombination and arrangement of the parts of a mechanism of this nature,substantially as will be hereinafter pointed out and finally embodied inthe clauses of the claim.

The invention is fully illustrated in the accompanying drawings,'whereinFigure 1 is a top plan View of a portion of.

a boat provided with my improved propelling mechanism. Fig. 2 is alongitudinal sectional view, somewhat enlarged, of what is shown in Fig.1; and Figs. 3, 4, and 5 are views of certain details involved in theinvention.

Projecting upwardly from the bottom a of the boat, being securedthereto, is a pair ofstandards 17, forming bearings for a horizontalshaft 0, that extends transversely of the boat and is held in place ineach hearing by means of a plate d, surmounting each standard andextending over the shaft. Said standards project upwardly through anopening 8, provided in the floor f of the boat. The edges of saidopening are shown as being broken away in Fig. 1 to clearly show inelevation the construction of the shaft-driving mechanism. Said shaftcarries a pair of spaced drums g, which are loosely mounted thereon andwhich carry on their adjacent faces spring-actuated pawls h, that engagethe teeth of ratchetwheels "i, which are keyed on the shaft 0. Forwardof the shaft thereis disposed, being supported upon the bottom of theboat, another pair of standards 3', said standards affording bearingsfor another shaft is, which Serial No. 723.890. (No model.)

carries segments Z, upon the periphery of each of which is secured astrap or band m, which extends rearwardly and is Wound about and asecured to the periphery of one of the drums g. Each strap or band wemay be adjustably secured to either the drum or the segment. I haveshown it as adj ustably secured to the segment by means of a thumb screw12, that is mounted in the periphery of the segment and penetrates alongitudinal slot 0 in the band. The segments are swung by means ofcranks p, which are suitably secured thereto for movement therewith andwhich carry foot-treadles g. It will be seen that by oscillating thesegments Z the consequent rotation imparted to the drums Q will effect,through the pawls and ratchet-Wheels, the rotation of the shaft 0.

In order to effectually produce a continuous movement in the shaft 0, Iprovide means for working the segments Z alternately, said meansconsisting of another band or strap 1", secured to and passing aroundthe peripheries of the drums g alongside of the other straps, and alsoextending around sheaves s, that are journaled in uprights t, suitablysustained between the fioor f of the boat and one of the thwarts u.

'12 is a propeller-shaft carrying a propeller w and journaled at itsforward end in a pair of standards y, that rest upon the bottom of theboat, that portion of said shaft between the standards y being formedinto a compound or reversely-threaded worm z. Said Worm is adapted to beengaged by either one of apair of worm-wheels a b, that are rigidlysecured upon a sleeve 0', said sleeve being keyed for movementlongitudinally thereof upon the shaft 0. It should be remarked that thewormwlieels a and b have their teeth cut right and left handed,respectively, being adapted therefore to rotate in opposite directionsthe propeller-shafto. In order to move the sleeve 0 on the shaft 0 so asto disengage the one of the worm-wheels and engage the other of saidworm-wheels with the worm z, and thus reverse the mechanism, I haveprovided a shifting lever 01, that is fulcruined in a suitablysupportedbracket e and is curved about said sleeve, being provided withdiametrically-opposing lugs f,which engage in a groove g, formed betweenthe worm-wheels. The

free or handled end of the lever projects forwardly, so that it can beconveniently reached by the operator from the thwart h, which it isintended he should occupy. A double stop 70', consisting of an elongatedplate of metal bent into substantially the shape of the letter M issecured, if desired, to the flooring f, beneath the lever, so as tomaintain the latter in either of the two positions where it effects anengagement between one of the wormwheels and the worm.

If it is desired to employ instead of the propeller side wheels, theshaftc may be extended beyond the Walls of the boat and carry such sideWheels, the same being shown in dotted lines in Fig. 1 and indicated bythe reference character 1', each being supported in an auxiliary bracketj, projecting outwardly from the boat.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In a mechanismforpropellingboats, the combination of a suitably-supported revolubleshaft,drums loosely mounted on said shaft, ratchet-wheels secured onsaid shaft, springactuated pawls carried by said drums and engaging theratchet-Wheels, means for operating said ratchet-wheels, asuitably-journaled shaft disposed transversely with reference to saidfirst-named shaft, a propeller carried by said last-named shaft, acompound worm carried by the propeller-shaft, a sleeve keyed onto saidfirst-named shaft, a pair of worniwheels having their teeth reverselycut and either being adapted to engage said worm, said Worm-wheels beingmounted on said sleeve, and means for shifting said sleeve on the shaft,substantially as described.

2. In a mechanism for propelling boats, the combination of asuitably-supported revoluble shaft,drums loosely mounted on said shaft,ratchet-Wheels secured on said shaft, springactuated pawls carried bysaid drums and engaging the ratchet-wheels, another shaft, segmentshaving hearings on said shaft, bands connecting said segments and thedrums, means for oscillating said segments, another band connected atits ends to each drum, sheaves, said last-named band passing over saidsheaves, a propeller, a suitably-journaled propeller-shaft carrying saidpropeller, a compound worm carried by said propeller-shaft, a sleevekeyed onto said first-named shaft, a pair of worm-wheels having theirteeth reversely cut and either being adapted to engage said worm, saidworm-wheels being mounted on said sleeve, and means for shifting saidsleeve on the shaft, substantial] y as described.

In testimony that I claim the foregoing I have hereunto set my hand thisth day of June, 1899.
